To a wmornit may concern;

Be it known that I, ABRAHAM TISMAN, a citizen of Russia, and residing at New York,

in the county of New York and State of New York, have inventedcertain new and usefullmprovements in Automobile-Bumpers, of which the fbllowing is a specification in the art a This in entionrelates to bumpers or but iers for power driven vehicles, and the object thereof is to provide improved devices for connecting a spring bumper or bufier with the chassis or framework of the vehicle which consist of two parts having no spring action and no spring connections'and with one of which the spring bumper or lender is detachabl-y connected andthe other of whiclr is'connected with the chassis or framework of the vehicle,' and with this and other objects in view the invention consists in devices of the class specified, constructed and operating as hereinafter described and claimed. p

This invention is an improvement on described and claimed in "U. S. Letters Patent. No. 1,220,571fgranted to me March 27, 1917 and said invention is fullydisclosed in the following specification, of which the accompanying drawing for'msza part, in which the separate partaof my improvement are designated by suitable reference characters in each of the views, andin which Figure 1 is a plan view showingmy improvement applied to a chassis or" truck frame of an automobile, part of thecon struction being broken away and part in t o a .1 -Fig-i2 aside viewof the construction shown'in Fig. 1-. and partially in section;

wand,

Figs-3 and 4 side'views of separate parts of the construction by which the bumper or lender is connected with the chassis or truck frame, one of said parts, being partially in section.

.In the drawing forming part of this specificatiom'l have shown at a a part of a chassis or truck frame of a power. driven vehicle, and said chassis or truckfirame is provided with forwardly directed side ex-,

tensions aof the usual form, andin the invention I secure to these parts ciarms having angular foot nieces practice of m that are passed 1 I), this connection being clearly shown in Figs. 1 and 2, in which the forwardly directed extensions a oi the chassis or truck frame are bent downwardly and the arms 6 are placed on the inner side thereof with the foot pieces'b fitting beneath said extensions, and thearms b are provided centrally with slots 6, and in the end portions thereof with transverse apertures 6* which form recesses the foot pieces 6 and I also rovide yoke-shaped clamps b, the side arms of which arepassed through the slots 6 and apertures btand are provided with nuts 6*.

By means of this construction the arms 6 may 'be quickly and easily attached to the extensions a of the chassis or truck frame and detached therefrom whenever desired or necessary, and said arms when in position are forwardly and upwardly inclined, and

:the front ends 0 the arms b are provided with circular hea members 6? having lock teeth 6 and the object of. the slots 6 in the arms a is to adapt said arms for use in connection with yoke-shaped clamps b 'of' intoloops' 0 provided with inwardly (ii-- rec ted members 0 bent at their inner ends to form loops 0* and outwardly directed spring arms 0.the end-portions of which are bent fierwardly as shown at 0?, and are adapted to bear on the parts c- When pressure of any kind is applied to the parts a", and the spring bumperor louder device 0 is connected wih the arms I) by means of,U-shaped clam I (2' into whichthe arms c of the bumper or ufifer device 0 are dropped and secured by means-of bolts 6, and-the U-sha d clamps a? are provided atone side thereo with short arms d having circular heads a? provided with lockteeth d which are adapted to engage the lock teeth 6 onthe head members 6' of the smash and'the head the arms d are-placed together as shownin Fig. l and secured together by halts)v which ria- - tions of which,

theirbuter ends withnuts 7 end by screens of this construction, or methodoii'eonneotion the spring bumper or butter device '0 maybe raised or lowered, or edyusted vertically'whenever desired. 1 also employ in connection with the main spring member 0 of the bumper or bufi er device it supplemental plate or leaf s ring member a wh ch is connected with the inner side of the spring member 0 by e, suitable clamp or keeper 0 through which it passes, and the end orcentrally thereof are ent backward to form loops 0 end forward to form spring end portions 0 which beer on the inner sides of the endportions of the spring members 0 and ere connected therewith by keepers 9 through which they pass and the parts 0 and a are also connected .by keepers g through which they pass.

The spring bumper or .buiier device 0 constructed in the manner shown and described ossesses the greatestpossible elasticity and resiliency 'in proportion to its weight, and the partsthereof will yield to the greatest possible extent without breaking and the device may be quickly and easily connected with, or detached from the chassis or-truck frame whenever desired, and the spring buffor device may be adjusted vertically to .anv necessary or desired extent.

It will also be seen from the foregoin descriptionthot the parts 6 of the spring huffor attaching devices are mo nted on the sides of the-side extensions a of the chassis freme end ere secured thereto, insteed of being mounted on the tops of said side ex-- tensions a as has heretofore been customary,

and while this connection is made on the inmr sides of the side extensions of, my 1n ventionis not limited to this errengement oiidthe parted may be mounted on the outer sides of said side extensionsge desired.

Having fully described my invention whet ll claim as new end desire to secure hv Letters Patent, is

1. In a bufier supporting means for connesting a buffer with the chassis or frame of a vehicle having projecting side members, arm plates provided at one end with latereliy directed feet which are'ed'epted to bev placed beneath said side members, saidat one end with e laterally directed foot member adapted to be placed beneath one or the eiitensions of the chassis, said part being secured to said extension by yoke-sheped bolts passed through apertures in said port, end-the other part of each member being odjustebly connectedwith the first named part and adapted to be connected to e, buder.

In testimony that l claim the foregoing as my invention 1 have signed my name inpresence of the subscribing witnesses this 11th day of August 1917.
